RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including extra-version. Try it out:
const version = require('extra-version');
var x = version.from('v1.2.3.4');
x.toString();
var x = version.from('0.2');
version.isUnstable(x);
var x = version.from('1.2');
var y = version.from('1.2.3');
version.compare(x, y);
var x = version.from('1.2');
var y = version.next(x, version.MINOR);
y.toString();
